After a very exasperated phone call explaining that the Olympics actually meant light traffic, we got a new (!) slot for the service team to come round. We were assured by both the booking person and the head of installation that we'd be the first call out this morning. Guess what? No-one had showed up by 11am. Or midday. In fact, they didn't show up until the middle of the afternoon, saying that there was nothing on the call sheet about us being the first call out. (What is wrong with this company?!)
Rob had worked from home so he'd be there to explain the problems himself. Apparently the service chap was perfectly lovely and agreed that Mastick, debris, unusual shrinkage etc were not acceptable reasons for the number of leaks we were enduring. He's going to order up replacement vents and metres of rubber and replace as much as possible. This will be a full day's job. (The last time Sunfold Systems were meant to do a 'full days work' it lasted for several days, so I won't hold my breath).
Fortunately we have a 10 year warrantee. I hope these leaks are sorted before the 10 years is up!
